Connecting the Power Terminal
• We recommended that you use the special red
battery and ground wire [RD-228], which is sold
separately. Connect the battery wire directly to
the car battery positive terminal (+) and the
ground wire to the car body.
• Recommended wires size (AWG: American Wire
Gauge) is as follows. The battery wire and the
ground wire must be same size.
• Use a 10 AWG to 20 AWG wire for the system
remote control wire.
Battery Wire and Ground Wire Size
Wire Length less than 3.6 m less than 6.4 m
Wire Size 8 AWG 6 AWG
1. Pass the battery wire from the
engine compartment to the interior
of the vehicle.
• After making all other connections to the
amplifier, connect the battery wire terminal
of the amplifier to the positive (+) terminal of
the battery.
2. Connect the wires to the terminal.
• Fix the wires securely with the terminal
screws.
WARNING
Failure to securely fasten the battery wire to the ter-
minal using the terminal screws could cause the ter-
minal area to overheat and could result in damage
and injury including minor burns.
3. Put the wire ties in the slits and
wrap the wire ties around the wires.
• Make sure the wires are connected and
attached properly before wrapping the wire
ties around the wires.
• Wrap the wire tie around the wire insulation,
not the stripped wire.
• Cut off any excess portions of the wire ties.
